Ceiling Table and Ceiling Formwork Comprising Such a Ceiling Table

ABSTRACT

The invention relates to a ceiling table (10) for a partial formwork of a concrete ceiling. The ceiling table (10) has at least one formwork element, in particular multiple formwork elements, which can be assembled on a lower frame (16) of the ceiling table (10) in a nondestructive manner and which can be disassembled from the lower frame (16). The ceiling table (10) has a support skeleton (14) on which at least one formwork element, in particular multiple formwork elements, is/are arranged. The support skeleton (14) can have multiple braces which can be connected together and separated from one another in a nondestructive manner. The support skeleton preferably has a pair of main supports, in particular parallel running main supports, on which a pair of edge supports and at least one central support that is arranged between the edge supports are arranged. The edge supports and the central support run preferably parallel to one another. The invention further relates to a ceiling formwork comprising such a ceiling table (10).

The invention relates to a ceiling table for a ceiling formwork, theceiling table having a lower frame comprising multiple supports. Theinvention further relates to a ceiling formwork comprising such aceiling table.

The use of formwork elements to build concrete ceilings is known. Inparticular, frame panel formwork elements are used that at leastpartially form a mold to be filled with liquid concrete. Once theconcrete has hardened, the formwork elements are removed.

Using the formwork elements, ceilings can be designed flexibly becausethe ceiling formwork is assembled from many individual formworkelements. To pour concrete quickly for large-area ceilings, it has beenproven useful to use ceiling tables that have a lower frame and a largeformwork surface. Such ceiling tables are brought to the next floorusing a transportation fork once the freshly poured concrete ceiling hashardened. The disadvantage of the known ceiling tables is that they arecumbersome to transport and can only be used in an inflexible manner.Furthermore, the known ceiling tables are often incompatible with otherformwork elements.

The object of the present invention is therefore to create a ceilingtable that makes it possible to quickly create a ceiling framework withmaximum flexibility. The object of the invention is also to provide aceiling formwork comprising such a ceiling table.

This object is achieved according to the invention by a ceiling tablecomprising the features of claim 1 and by a ceiling framework comprisingthe features of claim 13. The dependent claims specify useful furtherdevelopments.

The object according to the invention is thus achieved by a ceilingtable comprising a lower frame having multiple supports. The ceilingtable has a support skeleton. The support skeleton is arranged or formedon the lower frame. Formwork elements are mounted to the supportskeleton. The formwork elements have a formwork element frame. Aformwork shell of the formwork element is arranged on the formworkelement frame. At least one formwork element is mounted to the supportskeleton in a reversibly detachable manner.

The ceiling table can be flexibly adapted to a building structure viathe at least one formwork element that is mounted in a reversiblydetachable manner. For example, the at least one formwork element thatis mounted in a reversibly detachable manner can be removed from theceiling table to create a cavity for a concrete column. Because of theat least partial disassembly capability of the ceiling table, theceiling table can furthermore be transported in a compact manner with atruck.

According to the invention, a ceiling table of a ceiling formwork is inparticular a (preferably rigid) unit for creating a ceiling formworkthat makes uniform implementation together with the supports of theceiling table and the formwork elements of the ceiling table possible.

The flexibility of the ceiling table is further increased if multipleformwork elements, in particular all formwork elements, of the ceilingtable are mounted to the support skeleton in a reversibly detachablemanner.

Alternatively or in addition to this, the lower frame can be arranged onthe support skeleton in a reversibly detachable manner.

The support skeleton can have a first main support and a first edgesupport that is mounted to the first main support in a reversiblydetachable manner. The support skeleton can be designed particularlyflexibly as a result.

The at least one formwork element is preferably rectangular.Furthermore, multiple formwork elements, in particular all formworkelements, are preferably rectangular.

The formwork elements can be identical in design to make theconstruction of the ceiling table easier.

To easily arrange the at least one formwork element that is mounted tothe support skeleton in a reversibly detachable manner and to be able toremove it from the support skeleton, the longitudinal axis of the firstmain support preferably runs perpendicularly offset relative to thelongitudinal axis of the first edge support.

The support skeleton can have a second edge support that is mounted tothe first main support in a reversibly detachable manner. Thelongitudinal axis of the second edge support preferably runs parallel tothe longitudinal axis of the first edge support.

In a further preferred embodiment of the invention, the support skeletonhas a second main support. The longitudinal axis of the second mainsupport can run parallel to the first main support. The second mainsupport can be mounted to the first edge support in a reversiblydetachable manner. Alternatively or in addition to this, the second mainsupport can be arranged on the second edge support in a reversiblydetachable manner.

To arrange multiple formwork elements on the support skeleton, thesupport skeleton can have at least one central support that is arrangedon the first main support in a reversibly detachable manner. Thelongitudinal axis of the central support can run parallel to thelongitudinal axis of the first edge support and/or parallel to thelongitudinal axis of the second edge support.

In a further embodiment of the ceiling table, the lower frame can havemultiple rolls such that the ceiling table can easily be displaced.

At least one formwork element, preferably multiple formwork elements, inparticular all formwork elements, can each have a coupling point, inparticular in the form of at least one locking projection, to arrange asupport head of the ceiling formwork. As a result of this, the formworksurface of the ceiling table can be expanded in a particularly flexiblemanner with further formwork elements.

Alternatively or in addition to this, at least one formwork element canhave at least one plastic corner. As a result of this, damaged cornersthat are especially at risk on formwork elements can be repaired easilyby replacing the plastic corner.

The object according to the invention is further achieved by a ceilingformwork comprising a previously described ceiling table, a support headand a further formwork element. The support head can be arranged to thefurther formwork element in a reversibly detachable manner as well asarranged on the ceiling table in a reversibly detachable manner. Theceiling formwork thus comprises a ceiling table that was expanded by afurther formwork element.

The ceiling formwork can have a ceiling support comprising the supporthead and a formwork support such that the further formwork element canbe supported on the substrate not only via the ceiling table, but alsovia the ceiling support.

First central support 26 a can, as a result, be arrangedon main supports 20 a, 20 b (see FIG. 4) in a simple manner—just likefirst edge support 24 a.

FIG. 6 shows a support skeleton 14 comprising multiple main supports 20a, 20 b as well as edge supports 24 a, 24 b and central supports 26 a-earranged on main supports 20 a, 20 b in a reversibly detachable manner.Longitudinal axes 28 a, 28 b of main supports 20 a, 20 b run parallel toeach other. Longitudinal axes 30 a, 30 b of edge supports 24 a, 24 b runoffset and perpendicular to longitudinal axes 28 a, 28 b of mainsupports 20 a, 20 b. Furthermore, longitudinal axes 32 a-e of centralsupports 26 a-e run offset and parallel to longitudinal axes 28 a, 28 bof main supports 20 a, 20 b. As a result, support skeleton 14 formsreceiving frame that can be expanded and reduced in size flexibly formultiple rectangular formwork elements 12 a-c (see FIGS. 7 and 8).

FIG. 7 shows first formwork element 12 a (see also FIG. 1). Firstformwork element 12 a has a formwork element frame 34. Formwork elementframe 34 preferably has at least one carrying aperture 36 a-d. Aformwork shell 38 is arranged on formwork element frame 34. Formworkelement frame 34 is made from metal, in particular from steel oraluminum. To manufacture formwork element frame 34 in a simplifiedmanner and easily repair damage to a corner of first formwork element 12a, first formwork element 12 a has plastic cladding 42 a-c on itscorners 40 a-d, only plastic cladding 42 a-c of corners 40-ac beingvisible in FIG. 7 due to the perspective representation of firstformwork element 12 a.

FIG. 8 shows support skeleton 14 according to FIG. 6 with formworkelements 12 a-c arranged thereon (see also FIG. 7). Formwork elements 12a-c are identical in design. In each case, two formwork elements 12 a-ccan be arranged between two central supports 26 a-e or between an edgesupport 24 a, 24 b and the central support 26 a, 26 e nearest to edgesupport 24 a, 24 b. Formwork elements 12 a-c can be mounted to supportskeleton 14 and removed from support skeleton 14 independently of oneanother.

FIG. 9 shows support skeleton 14 according to FIG. 8 with all formworkelements 12 a-l that can be attached to support skeleton 14. Formworkelements 12 a-l can optionally be inserted between central supports 26a-e or between central supports 26 a, 26 e and edge supports 24 a, 24 bnearest to them. The locking of formwork elements 12 a-l is done via endstops 44 a-e of central supports 26 a-e that are releasably screwed on,of which only the end stops 44 a-e arranged on central supports 26 a-eat one end are visible in FIG. 9 (see also FIG. 6 with respect to theend stops arranged at the other end). End stops 44 a-e are preferablyplate-shaped.

FIG. 10 shows a ceiling formwork 46 comprising ceiling table 10.According to the illustration in FIG. 10, further formwork elements 48a-c can be added onto ceiling table 10. Other formwork elements 48 a-care connected to ceiling table 10 via support heads, only the supportheads 50 a, 50 b used for attachment to ceiling table 10 being visiblein FIG. 10 due to the perspective representation. Support heads 50 a, 50b connect formwork elements 12 g, 12 k to other formwork elements 48 a,48 b.

Formwork elements 12 a-l are identical in design to other formworkelements 48 a-c. Both formwork elements 12 a-l and other formworkelements 48 a-c have coupling points (see coupling points 56 a-daccording to FIG. 11) for the connection of a support head 50 a, 50 b.Support heads 50 a, 50 b are arranged on formwork supports 52 a, 52 b.Support heads 50 a, 50 b form ceiling supports 54 a, 54 b together withformwork supports 52 a, 52 b.

FIG. 11 shows by way of example further formwork element 48 c toillustrate the flexible connectability of further formwork elements 48a-c (see FIG. 10) to formwork elements 12 a-l (see FIG. 10). In FIG. 11,formwork shell 38 (see FIG. 7) is not visible. It can be seen from FIG.11 that the further formwork element 48 c has coupling points 56 a-d inthe area of its corners 40 a-d. As shown by way of example withreference to coupling point 56 a, coupling points 56 a-d preferably havelocking projections 58 a-c. Coupling points 56 a-d provide thepossibility of a corner connection of a support head 50 c-f. It can beseen from FIG. 11 that support heads 50 c-f can be mounted on furtherformwork element 48 c with various degrees of engagement such thatrespective support head 50 c-f can support different numbers of otherformwork elements (not shown in FIG. 11).

Further formwork element 48 c has middle coupling points 60 a, 60 b tomake central support of further formwork element 48 c possible viasupport heads 50 g, 50 h.

Support heads 50 a-h (see also FIG. 10) of ceiling formwork 46 (see FIG.10) are preferably identical in design.

FIG. 12 shows a ceiling table 10. Ceiling table 10 corresponds toceiling table 10 according to FIG. 1. However, formwork element 12 j(see FIGS. 9 and 10) was not mounted. As a result of this, ceiling table10 can be used at the construction site despite a concrete column 62.

FIG. 13 shows a ceiling formwork 46 in which two ceiling tables 10 arefitted together according to FIG. 12 to frame concrete column 62.

When viewing all figures of the drawing together, the invention relates,in summary, to a ceiling table 10 for the partial formwork of a concreteceiling. Ceiling table 10 has at least one formwork element 12 a-l, inparticular multiple formwork elements 12 a-l, that can be assembled on alower frame 16 of ceiling table 10 in a nondestructive manner and can bedisassembled from lower frame 16.
